Astronomers Search for Galaxies at the Beginning of the Observable Universe

 

943148_1_1023-WBIGBANG-3_standard

 

Searches for the most distant galaxies have now probed earlier than the first billion years in the history of the universe, early enough to start seeing the primary effects of the first stars: the reionization of neutral atoms. Astronomers want to understand how galaxies formed and evolved in this period, the timescale over which this reionization took place, the nature of the objects that provided the ionizing photons, and the scenarios in which galaxies and their interstellar medium (ISM) become enriched with atoms made in stellar furnaces.

The Habitable-Zone Planets of TRAPPIST 1, a Solar System Twice as Old as Ours --"Life There Could Have Survived Billions of Years Beyond That On Earth"

"If there is life on these planets, I would speculate that it has to be hardy life, because it has to be able to survive some potentially dire scenarios for billions of years," said Adam Burgasser, University of California, San Diego.

Life After Death? --Physicists Says "It's Quantum Information that Transcends from One World to Another" (VIEW Weekend 'Galaxy' Stream)

While scientists are still in heated debates about what exactly consciousness is, the University of Arizona’s Stuart Hameroff and British physicist Sir Roger Penrose conclude that it is information stored at a quantum level. Penrose agrees --he and his team have found evidence that "protein-based microtubules—a structural component of human cells—carry quantum information— information stored at a sub-atomic level.”

The Largest Volcanic Region on Earth Discovered Buried Beneath Antarctica's Ice  --"100 New Volcanoes Revealed"

Scientists have uncovered the largest volcanic region on Earth  – two kilometers below the surface of the vast ice sheet that covers west Antarctica. The project, by Edinburgh University researchers, has revealed almost 100 volcanoes – with the highest as tall as the Eiger, which stands at almost 4,000 meters in Switzerland. Geologists say this huge region is likely to dwarf that of east Africa’s volcanic ridge, currently rated the densest concentration of volcanoes in the world.

A new experiment set for an Aug. 14 launch to the International Space Station will provide an unprecedented look at a rain of particles from deep space, called cosmic rays, that constantly showers our planet. The Cosmic Ray Energetics And Mass mission destined for the International Space Station (ISS-CREAM) is designed to measure the highest-energy particles of any detector yet flown in space.

Seth Shostak, SETI Institute Senior Astronomer and his co-host Chuck Nice welcome Jason Wright, Associate Professor of Astronomy at Penn State, to explore the exoplanets. Jason, who is a member at the Center for Exoplanets and Habitable Worlds, offers his insights on the important discovery of Proxima b, the neighboring exoplanet to Earth, roughly 4 light years away.

"Technological Civilizations Should Go Extinct After 200 Years" --An Astrophysicist Answers the Fermi Paradox (Today's 'Galaxy' Stream)

Our universe is incomprehensibly vast, with billions of other planets circling billions of other stars. The potential for intelligent life to exist somewhere out there should be enormous. According one astrophysicist at the University of Arkansas, we became "technological" after the industrial revolution and the invention of radio, or roughly 100 years ago. According to the principle of mediocrity, a bell curve of the ages of all extant technological civilizations in the universe would put humans in the middle 95 percent. In other words, technological civilizations that last millions of years, or longer, would be highly atypical.

In 1887, American astronomer Lewis Swift discovered a glowing cloud, or nebula, that turned out to be a small galaxy about 2.2 billion light years from Earth. Today, it is known as the "starburst" galaxy IC 10, referring to the intense star formation activity occurring there.

Is China's Fleet of Underwater Ocean Drones for Science, or Military Power?

China has deployed underwater drones -torpedo-shaped vehicles — called Haiyi, or sea wings in Mandarin- in the strategic South China Sea waterway for scientific purposes where they will remain underwater for a month, according to reports. In March, one device hit a depth of 6,329 meters, breaking an earlier record held by a U.S. vessel, Xinhua said. But observers ask is the technology actually being used as a political and military tool to secure its territorial ambitions. Beijing claims a massive section of the South China Sea that extends roughly 1,000 miles from its southern shores.

"Today the moon's field is essentially zero," says Benjamin Weiss, professor of planetary sciences at MIT. "And we now know it turned off somewhere between the formation of this rock and today."
